Displacement

Distance– The length of the path covered by a moving object in a given time is called the distance traveled by that object.




                        Distance = Speed × Time


Displacement– The difference between the final and initial positions of an object is called its displacement.




Speed – The distance traveled by an object in unit time is called the speed of the object.




                              Speed = Distance × Time


In the S.I. system, the unit of speed is meter per second (m/s).


Velocity – The displacement of an object in unit time is called its velocity.



         Velocity = Displacement / Time Interval


In the S.I. system, the unit of velocity is meter per second.


Acceleration – The rate of change of velocity of an object is called acceleration.


  Acceleration = Change in Velocity / Time Interval
